I am working on a patch to support 12v slot AC cycle in x86-power-control.This can be enabled by configuring slotACPowerName in json config file.Since you are also working on similar kind of feature in x86-power-control, I would like bring up this discussion on mailing list to understand how these two features, and the design you proposed for chassis reset are intended to work together.Kindly go through my design changes below and share your thoughts.
I have modified the existing /xyz/openbmc_project/state/chassis0 object to implement 12V On, Off, and Power Cycle for system which has 12V Slot power support.
If slotACPowerName is disabled and if,
RequestedPowerTransition = "xyz.openbmc_project.State.Chassis.Transition.Off" then poweroff [existing functionality not changed]
RequestedPowerTransition = "xyz.openbmc_project.State.Chassis.Transition.On" then powerOn [existing functionality not changed]
RequestedPowerTransition = "xyz.openbmc_project.State.Chassis.Transition.PowerCycle" then PowerCycle [existing functionality not changed]
events will be called.
If slotACPowerName is enabled and if,
RequestedPowerTransition = "xyz.openbmc_project.State.Chassis.Transition.Off" then 12V Ac Slot Off
RequestedPowerTransition = "xyz.openbmc_project.State.Chassis.Transition.On" then 12V Ac Slot On
RequestedPowerTransition = "xyz.openbmc_project.State.Chassis.Transition.PowerCycle" then 12V Ac Slot PowerCycle
events will be called.
